Clasp envelopes are made with sturdy manila material to ensure more protection to the enclosed materials and can be used for home or business use. There is a small, bendable metal clasp that holds the sealed part of the envelope in place. Tape can be put over the clasp to prevent the clasp from catching onto other materials.

Things You Will Need
Put your material into the envelope and address the front side.
Wet the gummed flap.
Squeeze the clasp by bending the metal part together and pushing it through the hole on the flap end.
Open the metal clasp and flatten it. Press the flap of the envelope so the envelope stays securely closed.
Take a piece of packing tape as long as the envelope is wide and tape the sealed flap closed. This will prevent the metal clasp from catching onto another piece of mail and opening.
Bring the envelope to the post office, weigh it, pay for the postage and drop it in the outgoing-mail slot.
